The SB2I is a
pressure die cast aluminium sensor housing (IP65) with two
integrated sensors for measuring inclinations and/or
accelerations along two axis.
As well as the sensors, the box contains two independent signal
conditioners, each with a 4...20mA, 2-wire output, and two
separate, highly stable voltage supply feeding off the
corresponding current loop, one for each sensor. Furthermore,
each signal conditioner includes an active low pass filter, whose
upper cut-off frequency / settling time can be adjusted to suit
the measurement task, an output stage with current limitation, a
noise voltage filter and a diode bridge for unipolar connection
to the current loop. Interference signals caused by unwanted
ground currents are eliminated by electrically isolating each
sensor and signal conditioner from each other and the housing.
A special electronic temperature compensation system can
significantly reduce the temperature sensitivity of the
implemented sensors. The compact PG cable gland and small housing
size in combination with the 3-wire connection enable the use of
this high quality measuring system in harsh operating conditions.

Application

The SB2I is
suitable for applications requiring precise inclination or
acceleration measurements along two axis under harsh
circumstances and returning of a 4...20mA output signal each.
Areas of successful implementation include construction, mining,
agricultural machinery, transportation and conveyor systems,
ships, operation and automation technology as well as general
mechanical engineering.
